Application filed June 3, 1908. SerialNo. 436,494.

To all whom it may concern:

Be it known that 1, JAMES KITGHIN, of New Glasgow, in the Province ofNova Scotia, Canada, have invented certain new and useful Improvementsin Heat-Retaining Covers, of which the following is a specification.

My invention relates to improvements in heat retaining devices, and theobjects of my invention are to provide a simple device of this class foruse on the top of stoves and the like, which can be used to cook or warmfoods, to warm dishes or otherwise retain the heat on the inside forsimilar purposes.

A further object of the invention is to adapt the device for use withdifferent sizes of dishes and to provide means for regulating the heaton the inside; and it consists essentially of a cover formed in aplurality of separable and superimposed sections, and regulatingventilating openings in certain of the sections, all as hereinafter morefully set forth and described inthe accompanying specifications anddrawings.

In the drawings, Figure 1 is a perspective view of a heat retainingdevice. Fig. 2 is a sectional view of the same.

In the drawings, like letters of reference indicate corresponding partsin each figure.

Referring to the drawings, it will be seen that the embodimentillustrated shows a heat retaining cover formed of two sections A and B,each consisting of two layers of thin metal, such as tin, a and b,spaced apart and formed with a dead air space 0 between, a layer ofasbestos c or other heat insulating I material being provided on theexterior of the inner layer.

The lower section A is annular in form, and provided with an open top, areduced portion (i, being provided around the edge and adapted to fitinto the bottom ofthe upper section B.

The upper section B is provided with a top e and a handle To retain thetwo sections together, rivets g are provided on the upper member, whichare adapted to enter into L-shaped slots h on the lower member. Theupper member has also provided therein, openings 7'. and 1'. formed inboth inside and outside layers and insulated from the dead air space bya cylindrical member 17, the opening on the outer layer being closed bya pivoted cover j or other means, the said openings being adapted toserve as ventilators, for the interior, the amount of ventilation beingregulated by the size of the opening.

In using the device with a high crock located therein, the two sectionsare employed, superimposed on each other as indicated in the drawings.Should, however, it be desired to cover a low dish, the upper sectionalone would be removed and used.

Theventilator enables the temperature of the interior to be adjusted, tosuit the purposes for which it is being used.

It will be evident that while I have described the cover as formed ofsheet metal and asbestos, it could be formed of any other suitablematerial, and other changes might be made in the details of theconstruction, without departing from the spirit of the invention.

What I claim as my invention is:

1. A heat retaining cover adapted to be placed on a stove, includingalower annular member having an opening at the top and bottom, the loweredge of said member being adapted to rest directly on the stove, and anup er member removably and closely fitted to t e lower member and beingprovided with a closed top the said upper member being adapted to beplaced on the stove, and used separately as a cover for small dishes.

2. A heat retaining cover adapted to be placed on a stove, including alower annular member having an opening at the top and bottom, the. loweredge of said member being adapted to rest directly on the stove, anupper member removably and closely fitted to the lower member and beingprovided with a closed top) the said up er member being adapted to eplaced on the stove and used separately as a cover for small dishes, andmeans for locking said members together.

3. A heat retainin cover adapted to be placed on a stove, inc uding alower annularmember having an opening at the top and bottom, the loweredge of said member being adapted to rest directly on the stove, anupper member removably and closely fitted to the lower member and beingprovided with a closed top, each of said members being formed of twothicknesses of metal with a dead air space between the said upper memberbeing adapted to be placed on the stove, and used separately as a coverfor small dishes. 10 In witness whereof I have hereunto set my hand inthe presence of two witnesses.
